The goal of this site is to provide a tutorial on how to use ffmpeg as a library. The real title is "An ffmpeg and SDL Tutorial", and the web page title is "ffmpeg tutorial". The link was posted here with only the subtitle, to make the post more alluring or mysterious (AKA clickbait).

The tutorial itself is solid, though it should probably mention the year of publication in the title - it was last updated in 2015, but it has been around since 2007.
